What Do You Need To Replace Your Air Filter?

Thus, replacing your air conditioner filter by calling professionals for AC service in Tempe, AZ, is one of the simplest ways to ensure that your system performs optimally year after year. The great news is that changing your air conditioning unit filter is a simple task if you understand what to do.

What do You Need to do to Replace Your Air Filters?

Here are some things you must do to replace your air conditioner air filters. 

  • Locate Your Air Filters

Determine the location of your air purifier. You may have better than one air filter to handle in your home. The air filter, air register, the air handler sideboard and even a window air conditioner unit will need to get replaced or cleaned.

Also, get the right sized air filter before replacing it and choose the same size when looking for a replacement home air purifier. Use a meter stick to measure the dimension, width and thickness of your air conditioner’s air filters and select a new filter using these numbers.

  • Replace the Return Air Duct’s Air Filters.

Remove the air filter’s locking mechanism. Wipe down the grill with soft microfiber. If the dust gets only between the slats, use a microfiber cloth wrapped around the edge of a flat screwdriver to clean softly between the panes, or vacuum the lid with a brush attachment. Add a new filter, making sure the air filter points in the right direction. Replace the air filter in the air duct, air handler cabinet, window AC unit, and furnace.

  • Change the Air Filter in the Air Handler Cabinet.

Turn off the HVAC unit’s electricity. If you’re unsure how to turn off your furnace, consult the owner’s manual and never use the air without a filter. Unhook or remove the door and wash as directed above. Examine the filter type. Replace it with a new filter in the appropriate size if it is disposable.
